autofluorescence

autofluorescence的音标为[ɔːtfluːˈɪzmɪnəs]，基本翻译为“自发荧光”，速记技巧为：auto-表示“自动的”，fluorescence表示“荧光”。

autofluorescence的英文词源是auto-（自动）+fluorescence（荧光）。这个词的意思是自身荧光。

变化形式：复数形式是autofluoroscences，比较级是autofluorescenter或autofluorescense，最高级是autofluoroscencest。

相关单词：

1. fluorescence（荧光）：来自拉丁语fluo，闪烁，加上-nes，表名词，所以荧光就是闪烁的东西。

2. intrinsic fluorescence（内在荧光）：来自拉丁语intrinsic，内在的，加上fluorescence，表示内在的荧光。

3. background fluorescence（背景荧光）：background表示背景，fluorescence表示荧光，所以背景荧光就是背景下的荧光。

4. fluorescence emission（荧光发射）：emission表示发射，荧光就是可以发射的东西，所以荧光发射就是指荧光物质发出光的过程。

5. fluorescence microscope（荧光显微镜）：microscope表示显微镜，fluorescence表示荧光，所以荧光显微镜就是用来观察荧光的显微镜。

6. autofluorescence microscopy（自发光显微镜）：autofluorescence表示自发光，microscope表示显微镜，所以自发光显微镜就是用来观察自发光物质的显微镜。

7. autofluorescence imaging（自发光成像）：imaging表示成像，自发光显微镜用来观察自发光物质，所以自发光成像就是指通过自发光显微镜成像的过程。

8. autofluorescence detection（自发光检测）：detection表示检测，自发光成像的结果就是检测结果。

9. autofluorescence spectroscopy（自发光光谱学）：spectroscopy表示光谱学，自发光就是指物质发出光的过程，所以自发光光谱学就是研究自发光物质发出光的光谱学。

10. autofluorescence imaging analysis（自发光成像分析）：分析是指对结果进行解读和判断的过程，所以自发光成像分析就是对通过自发光显微镜观察到的结果进行解读和判断的过程。

autofluorescence常用短语：

1. autofluorescence imaging

2. autofluorescence detection

3. autofluorescence measurement

4. autofluorescence emission

5. autofluorescent signal

6. autofluorescence emission spectrum

7. autofluorescence background

例句：

1. The sample exhibits strong autofluorescence under excitation with blue light.

2. The autofluorescence signal is used to identify the presence of a particular chemical in the sample.

3. The autofluorescence emission spectrum of the sample indicates the presence of multiple chemical species.

4. The autofluorescent signal is used to determine the age of the sample.

5. The autofluorescence background must be carefully removed from the image for accurate analysis.

6. The autofluorescence imaging technique is a powerful tool for studying biological tissue.

7. The autofluorescence of skin is used to determine the health status of the skin.

英文小作文：

Autofluorescence plays a crucial role in many fields of science and technology, from biology to medicine and beyond. It allows us to identify the presence of certain chemicals in a sample, determine its age, and even assess the health status of the tissue under examination. However, it can also pose a challenge when dealing with images containing strong autofluorescence background, which must be carefully removed to obtain accurate results. Nevertheless, the autofluorescence imaging technique is a powerful tool that allows us to gain a deeper understanding of the world around us and unlock secrets that were previously hidden from view.
